Description

technical field [0001] The present invention relates to a manifold for double-stack fuel cells arranged side by side and to double-stack fuel cells. Background technique [0002] Since the invention of the fuel cell by British chemist William Grove in 1839, the fuel cell has been in the research stage. Until the 1960s, the United States used fuel cells on space shuttles, which promoted the further development of fuel cells; in the 1970s, the oil crisis occurred, and various countries realized the importance of energy, and formulated various energy policies to reduce the demand for oil. Dependence; By the 1980s, people's awareness of environmental protection was on the rise, which prompted developed countries to seek efficient and clean energy and develop new energy industries. [0003] At present, fuel cells (proton exchange membrane fuel cells) are widely used in the field of vehicles, bringing revolutionary breakthroughs to the development of the automobile industry, and ...
